Terminal text to speech silence

[mrphdes]

Hello!
Does anyone have an idea of how to input a time defined silence in the terminal text to speech for OS X 10.8?

I don't really understand what do you want, but if you type say "", it will speak silence.

2nd that, I also have no idea what you mean, sorry.
